Following the Chernobyl accident, authorities officially designated an exclusion zone around the plant where restrictions on public access and inhabitation are in place. This is where specially equipped unmanned aerial vehicles have spotted previously unknown areas with significantly greater levels of radiation. A British research team claims to have discovered unexpected radioactive hotspots near the Chernobyl ground zero, three decades after the worst nuclear accident in history. The hotspots were identified by a suite of drones capable of detecting radioactive gamma particles and neutrons, the University of Bristol announced. The drones carried out surveys within the Chernobyl exclusion zone, a largely inhabited area within a 30km radius of the failed reactor. The team flew 50 missions over the area over 10 days, mapping the so-called Red Forest, the ghostly 10-square-kilometre woodland around the plant considered to be one of the most contaminated places on the planet.
